On the final leg of his three-day visit to China, Macron urged leaders from other European Union countries to be more careful about the assets they allow to be taken over.

"Europe has often shown itself divided about China," Macron told the French community in Beijing. "And China won't respect a continent, a power, when some member states let their doors freely open."

Macron is pushing for foreign investment in strategic sectors in the region to be screened at the EU level, but many poorer EU member states who rely on Chinese investment have sought to water it down.

"China, which is a great power, does not respect a country that sells its essential infrastructures to the lowest bidder," he said.

EU hopes its negotiations on an investment pact with China will reach a "decisive stage" this year, the EU ambassador to the world's second largest economy said separately on Wednesday, calling on Beijing to honour its pledge to open its economy to the world.
